The d-metals can be mixed together to form a wide range of alloys because:
1. the range of d metal radii is not very great.
2. the d-electrons interact strongly with each other.
3. the d-metals have low melting points.
4. the d-metals have a wide range of metal radii.
5. the nucleus is well shielded by the d electrons.

the range of d metal radii is not very great.

Explanation:

The difference in metallic radii are not great hence the metallic ions are almost similar in size across the series. As a result of this, they can easily take up positions in the lattice of other transition metals leading to the formation of transition metal alloys. This explains the wide range of transition metal alloys used for various purposes in industry.

thats a little if u want the answer just look it up on google thats what i do haha : )

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
